Untouched and pure, as in "virgin snow." Virgins are new to an IRC channel or a given community. When virgins innocently violate unspoken rules of netiquette, those experienced with the internets flame them into a smoking pile of greasy ashes, much like the NRA encountering Bambi.
Because of their boorish behavior, virgins can appear to be trolls. However, trolls are consciously obnoxious for the lulz while virgins have no idea they are idiots. Savvy trolls will often create a sock puppet who pretends to be a virgin.

You don't have to be a slut! Instead, you can live a bone-dry life that is bereft of disgusting penis snot that will try to cry its way up your uterus. Yes, you too can be a virgin for the rest of your life!

Not much is known about virgins because those who are virgins typically claim that they are really sex fiends. Scientists speculate that most virgins are actually recluses who have small penises. Female virgins often complain about it on their blog.
